- Episode 1, while rather nice overall, starts off with a rather chilling moment with Tari waking up in the middle of a dark lab, as we're treated to brief clips of Dr Sheridan talking to Tari in the past. However, it's the last clip that's VERY notable as we're treated to what appears to be a disaster occurring in his lab, he's panicking and desperately trying to shut off the source of the disaster, before appearing to die caught in an explosion. Even worse, we a hear a terrified woman (later confirmed to be Lucinia) crying out to him for help before the flashback ends.
- Episode 2 shows just how harsh Lucks can be with his methods, as he has assistants forcefully tinker with Tari's cybernetic arm while she's still in Ultra Jump Mania. The result is Tari feeling every bit of pain from the tinkering in the game, with Lucks not hesitating for a second with his research despite Tari's cries of pain.
- While Luckss scientists experiment on Tari, the entire world of Ultra Jump Mania glitches, like reality itself is becoming unstable.
- Also occurring during the experiment is the appearance of glowing, circuit-like lines that appear and spread across Taris body, as if something is building up inside her. The others, for various reasons, pay no mind to this detail... until Taris forced exit of the game causes her body to release this energy as a HUGE shockwave, blasting everyone around her. One shot is dedicated to a scientist getting violently thrown into a wall by the explosion. No serious damage from the blast is made explicit and Theos arrival quickly distracts everyone, but its still an unnerving moment and the lack of explanation for what just happened arguably makes it worse.
- Episode 6 reveals that Dr. Sheridan was Laughing Mad through the entirety of the development process of Project Blue. The implications this has on the ethical aspects of the process are... disconcerting, at the very least. Especially with that explosion at the end... It's also revealed the woman we hear screaming in the footage is not Tari, but Lucinia, Belle's old best friend, meaning she presumably died in the explosion as well.
- Episode 8, while for the most part rather casual, has a rather tense moment when Tari warps into the Tempest tournament server. The transition seems to be normal... Until the scene starts to glitch out, soon ending up with Tari appearing in a strange black void with white particles floating about like snow. She eventually finds what appears to be Lucinia floating in the void with her, and when trying to talk to her, she just... drops out of Tari's view before she wakes up in the game. It all gives off an ominous vibe that leaves the viewer tense and wondering what the hell just happened.
- Episode 10 has Lucks at his most vicious. He shoots Masa's Meta Runner arm off and threatens to execute him if Sofia didn't turn herself in (As in he had his gun set to Masa's head), breaks Theo's cartridge and holds its chip, and by extension Theo, hostage, and forces Tari to surrender herself to TASCorp and have MD-5 stay away from him and TASCorp or he'll erase Theo.
- A teaser for Season 2 at first looked like a simple video of Simple Flip Island... then the screen starts to glitch out as we hear Theo begging for help, screaming "I want to go home!". Transfer Student gives some more context to the teaser, as it ends with Lucks moving Theo from the solitary chamber to a copy of his home... an extremely glitchy and terrifying version filled with horrifying facial expressions as enemies appear around him while he's stuck in the floor and his only weapon had glitched out of existence moments before. The last we see of him before the credits is him cowering in fear as the enemies begin merging together, towering over him.
- Season 2 Episode 9, which is fittingly entitled Nightmare Mode, gives us a look at the Glitchemoth, the glitchy abomination Evelyn takes control of to fight Tari and Theo in the glitched Ultra Jump Mania cartridge. It can only be described as a monster made of the tree enemies and even one of Evelyn's own arms sprouting from its body. And when Evelyn speaks through it, it sounds just as freaky too, almost like multiple voices are talking at once.
- Lucks' death in the season 2 finale. While not explicitly gruesome, it was definitely unexpected, and we even see blood spout out, some of which lands on Masa's face and the reactions on everyone's faces implied he was shot badly.
- Dr. Sheridan's brief appearance during The Stinger in Season 2. The tone in his voice is somehow even more unhinged than before, he has some noticeable burn marks across the left side of his face, and he's convincing Evelyn to join his side with promises of vengeance to the girl who humiliated her. Said girl is his own creation, by the way. With the confirmation that Season 3 is in the works, who knows what horrible things the two will do together?
- The fact that Sheridan was Masa's neighbor from "Firewall" and had been making several blink-and-you'll-miss-it cameos throughout all of Season 2.
